As far as the software goes, absolutely. The Wii U offers some of the best games on the market, period. As of when this post is written, the Wii U still has the best games of the generation (that may change since there won't be more Wii U games, and the PS4 is still getting games).
There is only one console you can play Xenoblade X, Fatal Frame: Maiden of Black Water, Bayonetta 2, Splatoon, and Mario Kart 8, and that's the Wii U. Ergo, hands down, the Wii U is the best console out right now. Not to mention the definitive versions of Deus Ex: Human Revolution, Smash 4, Zombi/ZombiU, and Monster Hunter 3U (which is just an upgraded version of Tri, but a far superior version).
I don't really get when people say the software was lacking. No, it didn't have FIFA, or Call of Duty, or Destiny. I guess people really love their shooters and only their shooters, and if that's the case, then yeah, sure, the Wii U had nothing for you. But if you actually like games, then the Wii U was for you.
I've said this in a dozen different threads: if you couldn't find ONE game on the Wii U you liked, among the ones I mentioned and MORE, then you don't like games. You can like games like the Witcher and Halo and still enjoy games like Topical Freeze or Splatoon. The argument that the games suck as you're playing your boring, rehashed games is stupid and it makes you sound like a moron.

As far as the hardware, no, I was not satisfied. Not because it was a weak console. I don't consider the PS3 or the X360 weak consoles. They're old. They're old in the sense that something newer and better has come out, but that doesn't make them bad, or weak, or crappy, or no longer satisfactory, or trash, or anything. They're just weaker. Outdated. That doesn't mean that they're no longer good.
The Wii U could have been better had it been more powerful. And I'm not just talking about the games, but that's mostly where power comes into play.
There was nothing wrong with the power the Wii U had. It just simply should have had more. It wasn't a good enough upgrade. It lacked. And it still produced some of the most gorgeous visuals I've ever seen. Bayonetta 2, Xenoblade X, and even MK8, had some breath-taking vistas. Those games weren't hurt by the Wii U's lack of power. They weren't worse because they didn't have the PS4's power. Could they have been better? Sure. But were they in some way made worse? No.
I was dissatisfied because of the missed potential. The GamePad was a farce, for example. It was a controller that had potential, and that potential was wasted.
We were also given a really crappy Virtual Console. And I only mean that in comparison to the Wii's, which was the single greatest collection of games in one machine the world has ever seen. The Wii U's VC was trash in comparison, as far as content.
tl;dr — The Wii U is one of my favorite consoles ever. It has some of the best games I've ever played on it. However, I can't help but feel it will always be known as the console that had all that potential, and that potential was killed off by Nintendo themselves.
